A series of europium(III) complexes with cyanoxime ligands were prepared. The IR spectroscopic data revealed that the ambidentate ligands were coordinated to the central europium(III) atom in either a tridentate or a bidentate manner. The Mossbauer isomer shift (IS) values showed a correlation with the quadrupole splitting (QS) values in all complexes. A plot of the IS values versus the QS values showed that with increasing electron density of the Eu(III) nucleus the symmetry of the electronic shell around the Eu(III) atom decreases.
